METAL DIAPHRAGM FOR CAR-VESTIBULES.

Application led July 15, 1914, Serial No. 851,034.

T0 all whom t may concern: i

Be it known that we, THOMAS WV. YOUNGER and OTTO B. SoHonNKY, citizensof the United States, and residents of the city of Sacramento, in thecounty of Sacramento and State of California, have invented a new anduseful Improvement in Metal Diaphragms for 'Oar-Vestibules, of which thefollowing is a specification.

Our invention relates to diaphragms for the vestibules of railwaypassenger cars.

One of the principal objects of our invention is to provide a diaphragmfor car vestibules which is cheap and durable and which is not liable tobe injured while in service.

Further objects are to attain certain advantages as will appear morefully hereinafter.

The invention consists in two arched metal plates which are secured tothe frame of a car and to the vestibule face plate respectively, andwhich t telescopically together to form a tight joint, while permittinga movement of the vestibule face plate to and from the frame of the car.

In the accompanying drawing, which forms part of this specification, andin which like reference characters refer to like parts throughout theseveral views, Figure 1 is a fragmentary view of the vestibule of apassenger car with a diaphragm embodying my invention applied thereto,the lefthand half of said Fig. 1 being an end elevation showing thevestibule face plate, and the right-hand half of said Fig. 1 being avertical section through the diaphragm; Fig. 2 is a fragmentary verticallongitudinal section through the middle of the vestibule of a passengercar showing the diaphragm applied thereto; Fig. 3 is a fragmentary topview of the vestibule of a passenger car, the left-hand half of saidFig. 3 being a plan showing the vestibule face plate and dia- Y phragm,the roof of the car being removed; and the right-hand half of said Fig.3 being a horizontal section through the vestibule face plate anddiaphragm, with parts of the floor of the vestibule and of the bulferplate broken away; Fig. 4 is an enlarged fragmentary horizontal sectionon the line 4 4 of Fig. 2; Fig. 5 is a fragmentary vertical sectionthrough the vestibule face plate and diaphragm.

. stems 3 are pivotally connected to the buffer plate 2 and are pressedoutwardly from the car by side buffer springs 5. Engaging the bufferplate 2 is a center buer stem 6 which is pressed outwardly from the carby center buffer springs 7 The upper part of the vestibule face plate 1is pressed outwardly from the car by two buffer stems 8 andcorresponding buifer springs 9. A. foot plate 10 is secured to the floorof the platform of the car and projects over the bu'er plate 2.

The diaphragm for the vestibule comprises a metal plate 11 which isarched or curved in an inverted U shape. One edge portion of the plate11 is bent at right angles to said plate and is fastened by screws 12 orother suitable means to the door frame 13 of the doorway in the outerwall of the platform of the car. Cooperating with the plate 11 isanother metal plate 14, one edge portion v of which is bent at rightangles to said plate 14, and fastened by screws 15 or other suit ablemeans to the vestibule face plate l. One of the plates 11 and 14,preferably the outer plate 14, fits telescopically within the otherplate. The free edge portion of each of the plates 11 and 14 has arebend 16 which contacts with the other plate. ln the upper face of theouter plate 14 is a water groove 17 which extends across the arched topof said outer plate, preferably near the outer edge of the other plate11, when said plates are in their normal position. A curtain 8 isarranged to be extended across the inside faces of the upright portionsof the plates 11 and 14 in the usual-way.

Asthe vestibule face plate 1 moves back andforth relative to the car,the plates 11 and 14 slide on each other to permit such movement of thevestibule face plate, while maintaining a tight joint between saidplates. The plates 11 and 14 may be made of any kind of metal, but arepreferably thin steel plates which are slightly resilient. Since thediaphragm is made of metal plates, it cannot be easily injured, eithermaliciously by tramps, or accidentally; nor can it be burned by hotcinders. A diaphragm of metal plates will be more durable and willwithstand the weather better than the cloth diaphragm now generallyused. The water groove 17 guides the water sidewise from the outer plate14 instead of against the joint between the plates 14 and l1.

l/Vhile a diaphragm embodying the invention has been shown applied tothe usual vestibule construction, it is not limited in use to thisconstruction. The plate l1 and the plate let may each be made ofseparate plates, if desired, instead of one plate, as shown anddescribed. Other changes may be made in the particular constructionwhich is shown and described without departing from our invention and wedo not wish to Copies of this patent may be obtained for be limited tothe details of this particular construction.

What we claim is:

A diaphragm for car vestibules comprising two arched plates ttingtogether telescopically and adapted to be secured between the vestibuleface plate and the frame of a car, the outer plate having a water groovein the upper face yof its arched portion.
